My current build with twisted 28g, 7 wraps each side, 2.5mm inside diameter, 0.54Ω. Any wider and I doubt it would fit inside the chamber without touching it. Actually is just a tad too warm for my personal taste, around 0.65Ω would be ideal.
Pic, followed by a word of caution:
See those two screws that are discolored? They used to be right next to each other... actually, they were touching, which was causing a short. I didn't realize it until I noticed how hot the pyrex
tank section was getting after a few hits. I switched the screws around but doesn't make much difference, there is barely any space between them. As I was setting up this current build on my
smok Xpro M80 Plus, it shorted again and "killed" it -- hopefully a simple fix.
Anyway, please do pay attention to the space between the inside positive screws and the outside negatives; I think mine may have made it through EH Pro's quality control when it shouldn't have. I'll be attempting to grind down one or both to create some room.
